Tunable magnetization steps in mixed valent ferromagnet Eu2CoMnO6

Abstract Magnetic properties can be manipulated to enhance certain functionalities by tuning different material processing parameters. Here, we present the controllable magnetization steps of hysteresis loops in double-perovskite single crystals of Eu2CoMnO6. Ferromagnetic order emerges below T C ≈ ...
